Template:STRUCTURE 2nad Formate dehydrogenase (FDH) catalyzes the reversible two-electron oxidation of formate to bicarbonate. The product electron is donated to either NAD+ in NAD-dependent FDH or to Mo-dependent FDH where the electron is donated to a Fe4S4 center and then to cytochrome. The Mo-dependent FDH-H from E. coli contains SelCys, Mo, molybdopterin guanosine dinucleotide (MGD) cofactor and Fe4S4.
